A Slingbox is a device that allows you to stream content from your computer to other devices, including Sony's PlayStation 3. This allows you to take a media file that exists on your computer and watch it on your television set without actually needing to burn that file to physical media like a CD or DVD. You can connect to your Slingbox with a PlayStation 3 using the game console's built-in web browser.
Turn on your Sony PlayStation 3 using the "PlayStation" logo button on your wireless controller.
Open your PS3's built-in web browser.
Select the "Address" option from the PS3 web browser main menu and go to "http://watch.slingbox.com."
Use the PS3's virtual keyboard (or an attached Bluetooth keyboard, if applicable) to type your Slingbox e-mail address and account password into the boxes on screen.
Click "Login" to connect to your Slingbox using your Sony PlayStation 3 home-video game console.
